h olding vious from the drawings. Whenthe upper and lower sashes are c' osed and the ton ue .1 2 lies on the face of the meeting i'a-i b, then if it be attempted to l'ft the lower sash, the upward movement of tie tongue` 1 2 will jam the locking' member 16 eaganst the rear wall of the box '10 and w ge soth'at no movement of the lower sash 'can4v possibly be secured. As a matter of fact, the weight of the 4member 16 will cause it to drop into wedging position so. that there is practically no movement possible for the lower sash, The same. thin is true of a downf ward movement oft e upper sash. IfY it be attempted to move the upper sash downward, the action will. be precisely the same as if the lower sash were moved'upward and the lookin member 16 will 'vedge in place,

tge two sashes fron'iany re ative movement., lIf it'be desired.v now to raise the lower sash or lower the uppersash, the op'.

eratorj by means of theistud 19 shifts the locking bar, wedge or tongue '16 o ver to the position shown in dotted i lines in Fi'g. 2,'v be lowered or the lower sash raised.' As the lower sash whereupon the upper sashmay is raised, however, relative to the upper sash, the tongue 12 will .be raised...A as shown in Fig.' 3, `and-the looking bar 16 "will be thrown over to.. the position shown4 in Fig. l3, restin against the rear face of the casing 10. `hisis a position of unstablefequilibrium and as soon as the lower sash is' lowered beyond the tongue 12, the tongue will .drop back 4again to the position shown in Fi 2 and-thewedgeor lockin member 16 wi l drop back to the position s own in Fig.

2, locking the two sashes from. any relative movement. Of course, '-tlie like operation will occur upon ay lowerin ofthe upper sash. It will be seen that t e rounded end l5 of the tongue. 12 will cause it to .ride smoothly along ing rail b so t sash is moved relatively'7 downward' .Y

,While'I have illustrated this device as applied to windows, it will be obvious that it ma be applied-in other situations where it is eSired-to locktwo members from relativel movement and it will also be seen that the device4 may not only be applied: to ordinary windows-but is particularly applicable to the windows of. storehouses, garages, barns and 4genera-1 farm windows. `,It will lalso be noted that it is impossible to open the inside face of the meetat there will Abe no chance of its wedgiiig or jamming. when lthe lower.'

this construction as a lateral pressure onl the tongue 12 will of course not atleet the lock in any 'way and an upper pressure on the tongue would simply 'act in the same manner as if`upward pressure was applied upon the lower sash.

It might be ossible, with the construction shown in iigs. 1 and 2, to insert an implement with a hook shaped end between the meeting rails of the sashesa and b and then work the hook shaped ends into posi'- tion bene'th the wedge 16 and then raise the wedge. in ake 'the tongue in the manner \sliown in Figs. 5 and 6 wherein the tongue 12 is shown as being provided with the upwardly pro1ecting, longitudinally extending flanges 20, which extend high enough to .guard or shield the spaces between the tongue and in order to prevent \this I may any member beneath the wedge.

It will be noted from Fig. 3 that the stud 19 prevents the tongue 12 from being turned to a vertical position or' beyond a vertical position so that when the lower sash is lifted, the tongue cannot be turned beyond its center and thus when the lower sash is lowered, the tongue will automatically fall toits locking position, that .is the position shown in Fig. 2.

It is to be noted that-if this screw 19 be removed orsuitably adjusted the tongue-and locking memberI may be turned up so that the. tongue will be disposed in a position inclined toward the rear wall of the casing 10 and thus will be heldin anf inoperative position. By adjusting the studv 19, however, it is ossible to limit the inward movement of tltongue 12 to -such a position that the free endof the tongue cannot be forced 'inward beyond a certain point sc that the iis bottom of the casing and normally disposed in a 'horizontal plane and projecting out of the casing, but movable' in a vertical plane to a position within -the casingand.a lockgravity to a horizontal position, said lookin ving member'hing'edlyg' mountedon the upper l face o f`the tongue. and .urging the tongue by clined and bearing againstthe rear face ofv` 1 the casing, there being means for preventing a the `outer, end of the tongue vfrom beingy moved, inward to la vertical pla-ne `intersecting the pivotal centerof the tc'pngue'to-there` by causethe tongue to `be constantly urged' by gravity to a horizontal positionf. y
